Parking lights out
Wife hit a pothole and now both front parking lights are out, everything else works including turn signals. I pulled pass bulb (cause it was easy to get to) and both sets of pins passed continuity tests. Searches here lead me to believe there is not a fuse for just parking lights. Maybe a ground but not familiar enough with MB platform to know where to start looking for one that would effect both lights. Looking for some direction as to where to start. Thanks

Lucky she didn't crack a rim and blow a tire to waste!
Every car HL options are very specific, I'd say pull your schematic matching your VIN, then start probing the DC power using the schematic.
Don't be surprised about both L+R sides working in tandem. HL issues get tricky really quick !
I am going to guess something's gone wrong with the control module either hardware or software. Try a simple reset with a sofisticated Xentry if electricals check out ok. Hopefully it was just a random loose connection event.
Problem could be happening in the systems ahead of headlights themselves (Lt sensr, Lt Sw, fSAM, ...)
🤞

Where can i find a wiring schematic based on my vin?
Going to have to dive in a little deeper into info about control module and xentry. My knowledge is limited to GM and and pre 1990 cars.

schematic sources...
the mostly accurate schematics are located in the WIS database available for download via eBay.
If you need quick access, subscribe to proprietary services from good old classic Mitchell or AllData.

This here has Front SAM N10/1 and engine computer N3/10 wiring schematic https://mbworld.org/forums/e-class-w...ml#post8388077
Use any mercedes VIN encoder to know what options you car has as per Data Card and then start at N10/1 and sort out which one fits your car.
Finding a suitable wiring schematic based on VIN is not an automatic process in MB WIS/EPC program, it is still manual and take a bit of work.
